I have had 2 children and am currently pregnant with my 3rd. I wasn't as fit when I was pregnant with my son as I didn't workout like I do now. I mainly walked a bit with my husband. Once I got pregnant with my first, I started doing pregnancy workouts and continued walking. I gained 33 lbs and felt like I had my old body back within a couple of weeks of giving birth.
After I delivered my son, I started working out a lot more. This is about the time that I found Cathe. I was in great shape by the time I got pg with my daughter. I continued working out throughout my entire pregnancy (not starting til 18 weeks due to a.m. sickness), not really with weights as I was still pretty new to them, but on a 6" step doing Power Max and Step Works as my main workout tapes and taking 4 mile fast walks with my husband and son. I gained 25 lbs with this pregnancy. When I was in L&D and they took my resting heartbeat, they kept asking me if 50 bpm is normal for me and were very impressed when I said yes. When I went to my daughters appt at one week of age, my husband said to the nurse, "Doesn't she look great?" and the nurse said "Yes. I was going to ask her if you guys adopted, but then I remember seeing on the chart that Dr Herron checked on Annelise in the hospital." I started easing back into my workouts around 2-3 weeks.
With this third pregnancy, I felt as if I was in the shape of my life. I am having a harder time working out this time around, I think mainly because I have so much more going on. I have 2 kids, my son is in school, my business has grown astronimically, etc. But I have been working out 3-4 times per week with more variety this time than last, and am still doing weight training. I have gained 12 lbs so far and am 23 weeks on Tuesday. I still fit some of my prepregnancy jeans that are extremely low rise, except I carry a lot of water in my legs when I'm pregnant (they've grown by 3 inches or close to it) so I don't like the way I look in them anymore. Luckily, I remember from my first 2 pregnancies that the water weight comes off very fast. I CAN'T WAIT!
Anyway, I highly recommend working out during your pregnancy. Overall, you will have more energy, feel better, & look better all the while increasing your health and that of your babies. Studies have shown an increase in intelligence in babies of mother's who exercised. You will also bounce back to your prepregnancy shape much faster as well.
